10 Best Mini Split Ac Unit For Semi Truck 2025 in the United States

The Treeligo 12V Truck Air Conditioner is designed specifically for vehicles like semi-trucks, RVs, and construction equipment, offering a solid 12,000 BTU cooling capacity. This allows it to quickly lower the temperature inside your truck cab, which is especially beneficial for long hours on the road in hot weather. It uses inverter technology, enabling the compressor to adjust its speed based on cooling needs, which helps save battery power and ensures quiet operation at around 45 decibels—similar to a quiet conversation. The AC is powered by a 12-volt system compatible with your truck’s battery and can run with the engine off to reduce fuel consumption.

Installation is straightforward thanks to included accessories and instructions, and the durable ABS plastic housing resists corrosion and weather damage, making the unit suitable for harsh environments. While the energy efficiency is limited with a 1-star rating and a SEER of 1, indicating higher power consumption compared to other units, this may be a factor if you rely heavily on battery power without frequent engine running. The noise level, although relatively low, might still be noticeable in very quiet cabins.

The unit offers remote control and multiple operating modes (energy saving, sleep, powerful), adding convenience and flexibility. It also features a dehumidification function that can help reduce moisture inside the cabin. Backed by a 1-year warranty and positive customer feedback, it serves as a reliable cooling solution for truck drivers seeking easy installation and dependable performance, though it may not be the best option if minimizing battery drain over long periods is a priority.

The BJTDLLX 12V Air Conditioner offers a solid cooling capacity of 11,000 BTU, which should be effective for semi-truck cabins needing quick relief from heat. Its energy efficiency is decent, with a SEER rating of 14 and a 5-star BEE rating, suggesting that it balances power usage well for a 12V system. Installation is straightforward with a screw-on type, but it may require professional help due to its size and weight (46.3 pounds). Noise level is 10 sones, which is average for truck AC units; it’s not very quiet but not excessively loud either, so some noise during operation is expected. The unit includes useful controls like a remote and digital display, making it easy to adjust settings on the go. It also supports multiple fan speeds and operating modes, which adds comfort flexibility.

The durable construction with quality materials like aluminum and copper wiring is a plus for long-term use in tough environments. Requiring a 1000W generator and a large battery could limit its use if your power source isn’t robust enough. This mini-split AC unit is a practical choice for semi-truck drivers who want efficient, fast cooling and have adequate electrical support, but it may not be the quietest or simplest option for those new to these systems.

The Aspligo 12V Truck Air Conditioner is a mini-split system designed for semi-trucks and similar vehicles like RVs, excavators, and buses. It offers a cooling capacity of 7200 BTU, which is effective for keeping the cabin comfortable in warm conditions. The unit runs on 12 volts, making it compatible with typical vehicle electrical systems. Its energy efficiency ratio (SEER) of 7.5 indicates moderate efficiency, balancing power use and cooling without being top-tier in energy savings.

Operating at about 50 decibels, this AC unit is relatively quiet for a truck air conditioner, contributing to a more pleasant driving and resting environment. Installation is easy, and the split system design helps improve airflow and heat dissipation, enhanced by a unique sun-shaped air outlet. The low noise function supports quiet operation when parked or driving with the engine off. Its size and weight are reasonable for the category but should be checked against space availability in the vehicle.

A key consideration is that the unit does not include refrigerant; users need to purchase and add R134a refrigerant separately. This process may require technical knowledge or professional assistance. The AC features standard controls, without advanced remote or smart features. This unit is a practical choice for truck drivers or operators seeking reliable cooling with straightforward installation, provided refrigerant charging is appropriately managed.
